On the walk to work, at the weight room or in the last mile.
Somewhere between first tries and finish lines.Pillow fights and pushing limits. That’s where you find fitness.
Every moment matters and every bit makes a big impact. Becausefitness is the sum of your life. That’s the idea Fitbit was built on—thatfitness is not just about gym time. It’s all the time.
How you spend your day determines when you reach your goals.And seeing your progress helps you see what’s possible.
Seek it, crave it, live it.
When it comes to reaching your fitness goals, steps are just the beginning. Fitbit tracks every part of your day—including activity,exercise, food, weight and sleep—to help you find your fit, stay motivated, and see how small steps make a big impact.
Fitbit Charge HR: Design
The Charge HR is available in a range of colours – black, plum, blue, teal and tangerine. The screen matches the colour of the band too, so it doesn't stick out like a sore thumb. Unfortunately the black version is so anonymous it rarely attracts questions or comments – genderless would be a better description than unisex.
That screen is a monochrome OLED display and it's fairly vibrant and easy to read, despite being absurdly small. Press the button to cycle though the time, daily steps total, distance travelled, calories, flights climbed and of course your heart rate.
Fitbit Charge HR: Activity tracking
Like every fitness tracker out there, the Fitbit Charge HR mainly keeps tabs on steps and calories. While tracked steps are never an exact science, over a 14,000 step day the Fitbit recorded in line with both the Garmin Vivosmart HR and the Misfit Shine, so we have no hesitation in giving this aspect a clean bill of health.
Now pay attention runners and cyclists: there's no GPS built into the Fitbit Charge HR, which puts it behind the likes of dedicated running watches and its big brother the Fitbit Surge.
Without GPS, the tracking of running and cycling is never going to be accurate in terms of distance or pace. An update released since launch means that the Charge HR does estimate distance, although the accuracy left a fair amount to be desired. A 2.1 mile run was guesstimated at 2.56 miles, which meant that the accompanying pace reading was also wrong. To some that's a big problem, to others it's nice to have an estimation of a Sunday run. You decide.
Fitbit Charge HR: Heart rate tracking
The main benefit of the Charge HR, however, is for other activities. While many GPS devices are so focused on running and cycling that they ignore gym work, the Charge HR embraces it, and enables you to get accurate details of your workouts via the optical heart rate monitor that uses a bright LED to 'see' the blood pulsing through your wrist.
We tested out the heart rate information both while out running on the roads and when strapped into some of the machines in the gym. Using gym bikes and weights where we were generally static we found the Fitbit Charge HR's bpm tracking to be spot-on against the machine's own tech, but when running results were fairly wide of the mark compared to a chest strap. That, presumably, is due to the extra 'noise' created when bouncing up and down on the road.
The Fitbit Charge HR will also measure your resting heart rate, which is designed to be taken as soon as you wake up. The idea is that as you get fitter the rate of your heart at rest will decrease. It's a great idea – and we love that Fitbit uses this metric – but, worryingly, the data wasn't correct. Our actual resting heart rate (measured via old fashioned pulse and the Garmin Vivosmart HR) was well below 54bpm. The Fitbit had it at over 68bpm in some cases. That's criminally wide of the mark.

So what can we conclude? Well, the Fitbit is a decent activity tracker but its heart rate tech really struggles. In terms of features it's pretty much on a par with the Garmin Vivosmart HR, which also struggled to match a chest strap for accuracy, but managed to be a more useful tracker of resting heart rate. Its heart rate tech can inform your workouts but it's far from an effective training tool.
Fitbit Charge HR: Sleep tracking
As we mentioned, sleep tracking is now performed automatically by the Fitbit Charge HR, which means no more missed nights of sleep.
It may surprise some, but Fitbit's sleep reporting is actually way more simplistic and static than any of its direct competitors. The graph shows a blue block, which is your sleep duration. The total time is listed in the app, along with the day's stats. The block isn't coloured to designate hours of deep or light sleep as with other sleep trackers, but there are lines that mark when you toss or turn.
It's a remarkably simplistic feature which is surprising for a leader like Fitbit, yet as we've repeatedly said, sleep tracking is one of the least useful elements of fitness trackers. There's very little to learn about your sleep patterns, short of making sure you get your eight hours every day – which the Fitbit is more than capable of.
If you're keen to see detailed sleep patterns, the Withings Activité Steel or Misfit Shine will do a better job.
Fitbit Charge HR: The app
While not as in-depth as the Withings Health Mate app, or as open as the Jawbone one, the Fitbit Charge HR's app is clean, simple and easy to use. It's also quick to sync, with no frustrating pairing problems.
When you open the app, you're presented with all your data from the day, including steps, heart rate, distance travelled, calories burned, stairs climbed, amount of 'active minutes', bursts of stopwatch captured activity and sleep.
There are plenty of metrics to sink your teeth into, and that's without the additional food tracking, food plans and weight tracking options which require manual daily inputs – a step too far for us.
Any metric can be tapped to show historical data, as well as weekly totals. That's especially useful for 'active minutes' which is the amount of time spent in the day with your heart rate elevated. Upping this total means you're getting fitter.
Delving into the app further will reveal plenty of controls, where you can fine tune the device to your dominant or non-dominant wrist, or turn on the caller ID notifications.
You can also challenge yourself to beat certain step goals in the challenges tabs, and even invite friends to participate, too. It's a good idea, although we were disappointed by the choice of goals. Each of the four challenges simply involves walking more, not burning more calories or racking up more active minutes of exercise. Those seem far more meaningful, and thus far, don't exist within the Fitbit app.
Fitbit Charge HR: Battery life
Given the continuous heart rate monitor flashing away under the device, battery life is impressive. You should be able to get five days easily from the tracker, and we found it easy to keep topped up.
Of course, after recently testing the Withings Activité and Misfit Flash – both of which boast battery life in the months rather than days – charging is a bit of a hassle. But neither of those devices can touch the Charge HR for its workout tracking.
Charging is via a proprietary cable that magnetically hooks into the back of the device. Of course, if you lose that cable, you're stuffed, but we're sick of complaining about this seemingly ubiquitous wearables issue, and it's not something confined to the Charge HR.
